Attributes and Constants

readonly attribute nsIPrintSettings nsIWebBrowserPrint::globalPrintSettings

Gets a "global" PrintSettings object . If one doesn't exist, it is created. This is the object that is returned each time after that. The settings are initialized from the default printer.

readonly attribute nsIPrintSettings nsIWebBrowserPrint::currentPrintSettings

Gets a pointer to the PrintSettings object that that was passed into either "print" or "print preview". This enables any consumers of the interface to have access to the "current" PrintSetting at later points in the execution.

readonly attribute nsIDOMWindow nsIWebBrowserPrint::currentChildDOMWindow

Gets a pointer to the current child DOMWindow that is being print previewed. (FrameSet Frames) Returns null if parent document is not a frameset or the entire FrameSet document is being print previewed. This enables any consumers of the interface to have access to the "current" child DOMWindow at later points in the execution.

readonly attribute boolean nsIWebBrowserPrint::doingPrint

TRUE if in Print mode, FALSE otherwise.

readonly attribute boolean nsIWebBrowserPrint::doingPrintPreview

TRUE if in PrintPreview mode, FALSE otherwise.

readonly attribute boolean nsIWebBrowserPrint::isFramesetDocument
